PERMANENT wAvER.

Application led March 12, 1927. Serial No. 174,766.

The present invention relates to a hair curler and more lparticularly to a hair curler of the type intended to produce a permanent wave in the hair.

The most desirable type of natural wave in the hair is a comparatively large, soft wave, without an suggestion of kinkiness, since this type tion of coiffures which accentuate the natural beauty of the face.

It isv contemplated in the present instance to wave hair by coiling the hair in the form of a substantially 'lat helix upon a device' which retains hair in said form, and applying heat -to the hair while thus retained in position to produce a wave therein.

In order to accomplish this object, there is provided, in accordance with one feature of the invention, a spool or bobbin having .a langeon either end thereof, and a casing adapted to receive said spool or bobbin, said easing having electrical heating elements therein to heat hair wound upon said spool.

These and other features o the invention will be more fully brought out inthe following description and the accompanying drawings, wherein:

Figure 1, is a view in section through the separated component parts of a spool upon which a coil of hair ma be formed.

Figure 2, is a longitudmal section through a casing for holding said spool.

Figure 3, is a view in section similar to that shown in Figure 2, showing the spool of Figure 1 assembled and in position within said casing. v

Figure 4, is a transverse sectional view through the spool with a coil of hair wound thereon; and l Figure 5, is a view in lower elevation of the structure illustrated in Figure 2.

Referring to the drawings in detail, Figure 1 shows the component parts of a spool used for winding hair into a fiat helical coil for waving, the spool being comprised of a base portion A having van internally threaded tubular shank 1 and an annular flange 2 extending outwardly from the lower end of the shank portion. A pair of circular washers 3 and 4 of absorbent material are-tof the same outside diameter as the flange 2 and are each provided with a central opening 5S-of a size to slip over the shank 1. A second ianged element B has a flange 6 thereon lthe same size as the flange 2 of the base member and is provided with4 a'central openo wave is adaptetd to the producing 7 ltherein of a size to freely slip over the -shank 1 of the base memberA. A cap member C is provided with a tubular central port1 on 9 having external threads thereon of a slze to threadedly engage the internally threaded portion of the base member A and- 1s provided with an encircling skirt portion 10 spaced outwardly from the central portion 9 thereof to rest upon the flanged element B to force it into closer relation to the ilange 2 of the base member A when screwed into posltlon upon said base member. A heatlng caslng D is provided having a cup-shaped receptacle 11 with a heating element 12 retalned in position in the closed end thereof by means of a transverse plate 13. The heating element 12is connected by conductors encased within a cord 14. to a suitable source of electrical current. The cup-shaped casing 11 has a'slot 15 in the side thereof of a size to receive a trough-shaped portion 16 extending outwardly from a closure member E which is slidably insertable within the cup-shaped casing D, as best illustrated in Figure 3. The closure member E comprises a shallow receptacle 17 in which a second heating element 18 is mounted connected to conductors enclosed in a cord 19 similar to that described for the element 12. A plate 20 covers the heating element 18 and is permanently united tothe sides of the shallow 1 member 17 as by crimping. A central post 21 is mounted upon the plate 20, said post being of a size to be freely insertable-.within the central aperture of the hair containing spool, when assembled. This central post transmits heat upwardly from the heating elementV by direct conduction which assists in heating the spool and hair wound thereon uniformly throughout.

A sliding ring 22 encircles the casing D to have a close sllding fit thereon, and is retained in position thereon by means of beads 23 and v24 near the upper and lower edges,

respectively, of said casing. A trough-V shaped extension 25 is provided upon one side of the ring 22 to register with the troughshaped extension 16 of the closure member E to grip the hair which projects from the casing when thc device is in position for operation and to aid in preventing the escape of steam from the interior of the device. Knobs 26 and27 are provided upon the casing D and upon the closure member E, respeetively, for manipulating the device and are preferably of a substance which is a'poor f conductor of heat so as to permit manipulattion of the parts to retainthe parts in posiing the device whenv the parts are-heated by tion by means of frictlon or`other s1m1lar ex the operationiof the heating elements. pedients, and it is, therefore, intended to prol In using the device the absorbent washers tect the invention with respect to such equlve 3 and 4 are`moistened with a suitable lsolualents as defined in the appended claims. 70
